Amelin

She's a member of the Dustyclock clan, though due to their history of misfortune she doesn't advertise it. She's sister to Dinpin the tinkerer, Nolrin the gunsmith, and Lumdin the druid. She always has a  bunch of alchemical reagents on her and her trusty bronzium pickhammer.

She's a chirurgeon, specialized in rejuvenation and regenerative alchemy. And research into anatomy and mutagens to help aid in the recovery of others has made her question the alteration of her own form. These changes can improve the physical form at the cost of mental ability, but unless she can make sure it is safe she will not allow anyone to suffer these drawbacks, as she continues to research it herself. 

Currently, she is a support NPC in my local tabletop Pathfinder game I am running.  She has been looking for specimens and samples that interest her,  offering potions in trade. She is now accompanying the group and has been seen taking the form of an elf with a case of the hiccups, each time shrinking a little.
